Professional Applications & Engineering Value

This 5/16"-18 UNC hex head screw is engineered to address critical challenges in industrial assembly and heavy-duty applications. The 18-8 stainless steel material offers exceptional resistance to rust and corrosion, making it suitable for outdoor, marine, or chemically exposed environments. Its partially threaded configuration provides a non-threaded shoulder for precise alignment and increased shear strength, reducing the risk of stripping in soft materials. The coarse UNC thread and external hex drive facilitate quick installation and removal, saving time in maintenance and production lines. With a 7-inch length and 80,000 psi tensile strength, it is ideal for structural frameworks, machinery, and equipment where reliability and longevity are paramount.

Specification Summary & Compliance

This product adheres to Class 2A thread fit per UNC standards, ensuring dimensional accuracy and interchangeability. It meets ASME B18.2.1 specifications for hex head screws and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for various industrial uses.
